FFlGEa PATENT HENRY II. WALKER AND FRANK D. WALKER, OF PHILADELPHIA,PENNSYLVANIA.

ADJUSTABLE SWITCHBOARD.

SPECIFICATION forming part of Letters Patent No. 597,228, dated January1 l, 1898.

Application filed September 23, 1897. Serial No. 652,680. (No model.)

To all whom, it may concern..-

Be it known that we, HENRY H. WALKER and FRANKD. WALKER, citizens of theUnited States, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Ad justableSwitchboards, which improvement is set forth in the followingspecification and accompanying drawings.

Our invention consists of an improved construction of adjustableswitchboard which can be cheaply manufactured and is especially adaptedfor use in places where it is desired to economize space.

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a plan view of an adjustable switchboard embodyingour invention. Fig. 2 represents a side elevation of the conductinghinge or joint employed.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A and B designate plates, the same having theconducting hinge or connection C common thereto, said hinge consistingof the member D, which is provided with the substantially parallelblades or wings E, said wings terminating in the socket G, which isprovided with an opening II therein, in which a conductor is adapted tobe inserted and held in position by a binding-screw .I or other suitablefastening device. The other member of the connection 0 consists of theblade or wing F, which is located contiguous to the wing or wings E andis readily movable relative thereto, said wing F having the socket Kattached thereto,which is provided with an opening L therein, in whichthe end of a conductor is adapted to be inserted and held in position inthe manner described with reference to the socket H.

The sockets G and K are attached to the plates A and B in any suitablemanner, and it will be evident that an electrical communication existsbetween the wings F and E under all conditions in whatever position theplates A and B may stand, said plates being readily adjustable withrespect to each other, as is evident. I

Having thus described our invention; what we claim as new, and desire tosecure by Letters Patent, is+

1. In an adjustable switchboard, a plurality of plates, wings attachedto the latter and adapted to contact with each other in whateverposition said plates may assume and means for making electricalconnections to said wings.

2. In an adjustable switchboard, a plurality of plates having socketsattached thereto, said sockets being provided with wings which areadapted to contact with each other in whatever position said plates mayassume.

3. In an adjustable switchboard, a plurality of plates, movablerelatively to each other, a socket attached to one of said plates andhaving a plurality of wings, and the other of said plates having asocket attached thereto, and provided with a wing adapted to engage saidfirst-mentioned wings, so as to form an electrical connection inwhatever position said plates are located with respect to each other.
